I_ShowErrorMessageBox for SDL interface

Browse source 
Handles showing the error message box on quit.
- Polite communication that the game fell over and that you (probably) didn't do anything wrong
- Accomodates pointing you to UNIXBACKTRACE and _WIN32 exchndl crash logs if relevant
- Points you to the specific dated and timed log file that contains the error
- Tells you that the vague and often confusing error message (like I_Error) is for a programmer, server host, or add-on creator
- Hee Ho!
